Investigation of the mobility of uranium(VI) in argillaceous rock at higher salinity
Fritsch, K.; Schmeide, K.; Bernhard, G.;
Argillaceous rock is considered as one of the possible host rock types for radioactive waste repositories. Therefore, it is necessary to examine the retention behaviour of argillaceous rock towards long-lived radionuclides, such as uranium. In this study, the 2:1 clay montmorillonite, consisting of an octahedral alumina sheet sandwiched by two tetrahedral silicate sheets, is used. The sorption of uranium(VI) onto montmorillonite is studied in NaCl, KCl, CaCl2, and MgCl2.
